In the terms of our Great Society the Hell's Angels and their ilk are losers - dropouts, failures and malcontents. They are rejects looking for a way to get even with a world in which they are only a problem.The Hell's Angels are not visionaries, but diehards, and if they are the forerunners or the vanguard of anything it is not the "moral revolution" in vogue on college campuses, but a fast-growing legion of young unemployables whose untapped energy will inevitably find the same kind of destructive outlet that "outlaws" like the Hell's Angels have been finding for years.
